Guest nbruch1939 Posted June 14, 2005 Share Posted June 14, 2005 This is the problem I have a 1994 TT Supra, When I floor it the first turbo spools up fine at the point where the Second turbo should kick in I loose all boost. Gauge reads 0 psi until I release throttle, I floor it again and it does the same thing . However, the strange thing is it doesn't do this all the time sometimes both turbos work fine. I read somewhere to put my car into ttc mode. I did that and turbos worked fine, but then I couldn't fine the link that stated what possible problems this eliminates. My car is a BPU running 17 PSI (when working right) Quote Link to comment Share on other sites More sharing options...

toyo rob Posted June 15, 2005 Share Posted June 15, 2005 check the pipe leading to the pressure tank, behind the injection side of the engine, 2 small pipes, they caused me a load of problems with mine leaking boost all over the place. if ur still standard seq then find Ian C and go to his website, loads of pic of whatand where the pipes are and lead. good luck Rob Quote Link to comment Share on other sites More sharing options...

Guest nbruch1939 Posted June 16, 2005 Share Posted June 16, 2005 Ok I checked all hoses and tubes, also I checked the actuators to make sure they were opening at the correct PSI. Plus I checked the pressure tank, everything checked out. Were do I go from here? Quote Link to comment Share on other sites More sharing options...
